[Xen-users] XEND fails to start (XEN unstable, SMP, x86_64)
Hi XEN Users,
I''ve searched the archives of this list but could not find anything on
this subject. I have a
64bit AMD platform on which I can prefectly run XEN (no-SMP) (domain0 and
domiansU) from unstable
tree. Since I have two processors I wanted to enable SMP (HT) in the dom0.
Everything boots nicely
but when I start xend (xend start) I don''t see the xend process? BUT
xcs, xenstored and
xenconsoled are running. In the /var/log/messages file I see this:
python[3058]: segfault at 0000000000000000 rip 0000000000000000 rsp
00000000408001d8 error 14

x86_64 GNU/Linux
[root@nexcom ~]#
In xend.log:

Any ideas what could be the problem?
Many thanks and best regards,
